Acknowledged broadcasting in ad hoc radio networks
We consider ad hoc radio networks in which each node knows only its own identity but is unaware of the topology of the network, or of any bound on its size or diameter. Acknowledged broadcasting (AB) is a communication task consisting in transmitting a message from a distinguished source to all other nodes of the network and making this fact common knowledge among all nodes. To do this, the und...
متن کاملRobust emulation of shared memoryusing dynamic quorum - acknowledged
This paper presents robust emulation of multi-writer/multi-reader registers in message-passing systems using dynamic quorum conngurations. In addition to processor and link failures, this emulation tolerates changes in quorum conngurations, i.e., on-line replacements of one quorum system consisting of read and write quorums with another such system. This work extends the results of Attiya, Bar-...
متن کاملGastrointestinal polyposis and PTEN mutations: an under-acknowledged diagnostic criterion
Methods Blood was collected for PTEN mutation analysis and medical records were requested to document diagnoses. Patients who are PTEN+ with ≥5 GI polyps, ≥1 of which is hyperplastic (hyp) or hamartomatous (ham, n=4) or who met relaxed ICC criteria (n=118) were analyzed. Upper and lower GI endoscopy and pathology reports were reviewed and findings are reported descriptively. Fisher’s 2-tailed e...
متن کاملWho gets acknowledged: measuring scientific contributions through automatic acknowledgment indexing.
Acknowledgements in research publications, like citations, indicate influential contributions to scientific work. However, acknowledgements are different from citations; whereas citations are formal expressions of debt, acknowledgements are arguably more personal, singular, or private expressions of appreciation and contribution. Furthermore, many sources of research funding expect researchers ...
متن کاملAcknowledged Broadcasting and Gossiping in Ad Hoc Radio Networks
A radio network is a collection of transmitter-receiver devices (referred to as nodes). ARB (Acknowledged Radio Broadcasting) means transmitting a message from one special node called source to all the nodes and informing the source about its completion. In our model each node takes a synchronization per round and performs transmission or reception at one round. Each node does not have a collis...
